Abstract :
Along with the increasing number of consumers using electricity in the work area of ULP Lemah Abang, especially in the lychee feeder, one of the distribution transformers, namely the PGCE transformer, is overloaded. Overcoming the overloaded transformer is by looking for additional substations and load breakage, distribution transformer substations with SNTR code. Researchers conducted a quantitative analysis of correlation. The quality of power distributed to customers properly in accordance with applicable standards in order to minimize or prevent damage. Parameters used to measure power quality are loading current, load imbalance, loading power and voltage drop. Before repairing the loading current 109% - 117%, load imbalance 2% - 4%, loading power 110%-118% and voltage drop 6% - 7%. After repairs are made to the PGCE transformer, the load current is 76% - 77%, load imbalance is 2% - 4%, loading power is 75% - 76%, voltage drop is 4% - 5%. And the addition of the SNTR substation loading current 64% - 66%, load imbalance 6% - 9%, loading power 63% - 65%, voltage drop 3% - 4%. So the conclusion is that after the insertion of the substation, the loading is in accordance with the 1995 SPLN and SE No. 0017.E/DIR/2014, which is below 80%.
